X-Message-Number: 32890 From: Date: Thu, 30 Sep 2010 22:08:47 -0400 (EDT) Subject: Reasons Why Uploading Is Unlikely, Ever Content-Language: en Reasons Why Uploading Is Unlikely, Ever Publication plan: My tentative plan is to email one Reason a week, to various venues, and use the intervening days to respond to comments on the latest. Preliminary: "Uploading" here means simulating a person in an algorithmic digital computer in such a way that a living person results, a conscious person. Some possible types of computer, such as those doing quantum computation, are disregarded because not enough is so far known about them. Thus I am considering only computers similar to those now in use, except for improvements in speed and storage capacity. It is generally believed that this type of computer, including Turing's paper tape computer, can compute anything computable. I'm sure that some readers/writers will disregard my delimitation of the topic and change the subject. I'll try to deal with that. Reason 1. A simulation in a digital computer is just a coded description. With unimportant exceptions, a description of a thing is not that thing, and encoding the description makes it worse. For example, I can write down the quantum description of a hydrogen atom in its ground state, but that writing on paper will not be a hydrogen atom. If I could write down the description of a water molecule, a collection of these would not be wet. Doubtless some would say that a simulated person could drink simulated water, but that would be a poor simulation of an argument.
